lo all Lo/wm t may concern:

Be it known that l, Puna-P M. Brien, `a citizen of thr` United States, and a. resident of Hartford, in the count-y .of Hartford and that dass of ,gages employed to indicate an amount v'of gasolene in a tank .and the object of my invention, among others, is to provide l a simple and .effective device of this class which will accurately indicate the amount Vof gasolene wit-hin the tank and which will f also attract .attention when the amount ofi v .the amount in quarters of the contents of gasolene -is getting lextremely low.

One form of device embodying my invention and :in the .construction and use of which the Vobjects above set ont, as well as others, may be attained, `is illustrated in the accompanying drawings, in which- Figure -1 is a View in horizontal section through a portion 'of a tank with my iinproved gage applied thereto. lFig. 2 is a view in side elevation of said tank.

In the accompanying drawings the numeral 5 denotes a tank having an .opening 6 through one wall.

A casing 7 is tightly secured to the outer surface of the tankas by means of a .flange S soldered or otherwise fastened in place, this casing having a reduced outer end 9 forming -a shoulder -on its inner and outer side. A supporting .base 10 is located within the casing, this base being struck to form from sheet metal and having a flange tightly tilting within the casing, being held in place by the closeness of its fit or by brazing or other fastening if desired. A dial .plate 11 is placed between the base and the shoulder above referred to formed on the inner surface of the casing, this shoulder providing an abutment against which the supporting base and dial rest. The dial may be secured to said base as byl means of clips 12 from the dial plate passing through the base and bent on the back side. The side -walls 13 of the base are of sufficient length 4secured to the spindle 15, the spindle, oat

` arm and pointer being, `in fact, `formed from a single piece or rod bent to proper shape .and its end being flattened to form the indicating pointer. A shield 19 is loosely mounted On said spindle and covers a sector 20 of contrasting color to that of the dial plate 11. A pin 21 projects outwardly from the face of the shield into the path of movement of the vhand or pointer 18, so l:that when the pointer reaches afcertain posit-ion it will encounter this pin and move 4the shield to uncover the coloredseotor and at a time when the gasolene in the tank is reduced toa certain point, say three-'fourths empty. Graduations 22 may he employed to denote lthe tank, the .last .quarter having gradua tions 23 to denote the condition of the contents of this quarter.

The casing 7 has a lip 24 projecting inward and forming a seat for a packing 25 and a ,glass ydisk 26, this packing and glass disk being clamped `firmly against the seat afforded by the lip 24, as by means of a flange 28 overturned from a collar 27 screw threaded on to the reduced outer end of the casing and seated against the'yf'shoulder formed'on the outer side of saidltzas'ng 'by said reduced end. This collar in a-ct i'forms a part of said casing, constituting the outer end thereof.

The spindle 15 is so located on the tank that when the latter is full the tloat arm .It will rest insubstantially a .horizont-al position, the 'float being pressed against thecovel of .the tank, :and `thus forcibly submerged. in vthe position ofthe parts show-n i-n Fig. 2 the parts have the position assumed when the oontents'of the tank have been partially removed. This disposition of the dial is of an advantage in determining the exact condition as to the quantity of the contents in .the ,tank at the time when the tank getting empty, as t-he distance the pointer will move when the last quarter part of the contents of the tank are being consumed will be greater than the distance it will move while the first quarter of the contents of the tank are being consumed, and greater t-hanfthe distance the pointer will move while any of the other quarter parts of the contents of the tank are being consumed. The forceful submergng et thefloat by reason of its contact with the top of the tank when the latter is full permits a reduction "of a part of the contents without any indication ot that fact by the pointer, which actis immaterial so far as the knowledge of its contents ie concerned, but whenthe last quarter part of the contents are being consumed it becomes material that the exact condition be known and in thus providing for the movement of the pointer a substantial distance, during this period one is erabled to determine to a nicety just how much ,of the contents remain, and' this factinay `be indicated'to a n'icety by the graduations 23.

I`do not consider that a device must be constructed exactly as illustrated and described herein, as this construction may be departed from to a greater or lesser degree and yet einbodyvthe invention.

I claim#- A -l. A tank having an opening .therethrough, a casing secured to and covering said opening, a spindle having one end projecting within the casing, a pivotal support vfor said spindle, a float and float rod supported by the spindle, an indicating hand secured to the spindle, a shield pivotally mounted o n the spindle and arranged to be engaged and moved by the indicating hand at a predetermined time, and a sector ot' distinguishing character covered by said shield.

-2. A tank having an opening through the wall thereof, a casing coverino vsaid opening, a spindle supported by said casing and with one end projecting thereinto, a float and float rod supported .by said spindle, an indicating hand secured to the spindle, a shieldpivotally mounted on the spindle, a stopto limit the downward movement of the shield, a pin mounted to impart movement of the pointer to the shield, and a sector of distinguishing character underlying said shield.

3. A'tank having an opening through its wall, a casing secured to the outer surface ofthe tank about said opening and havin g a shoulder facing inward, a supporting base snugly fitting wit-hin said casing against said shoulder, a sleeve Vrigidly secured to and projecting from said base, a spindle supported in said sleeve, a float arm secured to` one end of the spindle and bearing a float, and a pointer secured to the opposite end of the spindle.

4. A tank having an opening through its wall, a casing secured to the outer surface of the tank about said opening and having an inward facing shoulder anda reduced outer end forming a shoulder, a supporting base snugly titted Within the casing againstsaid inward facing shoulder, a'spindle pivotally supported in said base, a float arm vsecured to one end ot the spindle and bearing a lloat, apointer secured to the .opposite end ot' the spindle, and a cap fitted upon the reduced outer end of the casing and resting against the shoulder on the' outer surface' thereof.

A tank having an opening through its wall, a casing secured to the outer surface of.

thel tank and covering said opening and having a shoulder on its inner surface, a supporting base snugly tted within the casing and. resting against said shoulder, a lip formed at the outer end of the casing, a glass resting against 'said lip forming a chamber between said glass and supporting base, a packing for the joint around said glass, 'meansfor holding the glass front against its seat, a pointer in said chamber, ya spindle bearing said pointer and mounted in the Support-ingebase, and a float arm secured to said spindle and bearing a float within said tank. t

6. A tank having an opening through the wall thereof, a casing secured to and covering said opening, a spindle having one end projecting within the casing, a. pointer secured to the opposite end ot' the spindle, a pivotal support for said spindle, a float and iioat arm supported by the spindle, a shield mounted in the casing and arranged to be operated by the movement of said spindle, and a sector of distinguishing character located to be covered and uncovered by said shield..
